ETHERNET PRINT SERVERS HIGH SPEED AND 4-PORT
12. The script creates a printcap entry for the printer just configured. The
screen displays an entry and asks if you want the script to append it to
your /etc/printcap file. The next page shows a sample printcap file.
All printcap entries must begin with a tab except for the entry on the first
line.
Like all BSD systems, ULTRIX uses the /etc/printcap file to configure a
printer. The interface to the installation script is the same for all BSD
systems, however, the printcap entry is different.
If you use the printcap entry generated automatically by the installation
script, this will be transparent to you.
ULTRIX uses dpifilter, a network-direct filter that sends standard input
directly to the Ethernet Print Server. Since ULTRIX accepts pipelines and
command-line arguments in the printcap input filter entry, this can be down
with no loss of flexibility. The input filter for an Ethernet Print Server on
ULTRIX must be piped into dpifilter. The arguments to dpifilter are the
Ethernet Print Server name and port number entered during installation.
The installation script generates the example shown below for a printer
connected to the Ethernet Print Server unit named DPIfast.
Any filter that works for a local ULTRIX printer can be used in place of
the infilter program.

PostScript Printing
When you configure an Ethernet Print Server printer, the TCP/IP install
script can create a printer entry in the /etc/printcap file. This default entry
uses the input filter supplied on the install diskette. With this entry, you can
print ASCII and PCL format files on PCL printers and PostScript format files
without banners on PostScript printers.
Most PostScript printers will not print an ASCII file. You must convert it to
PostScript format first. There are a variety of filters that can accomplish this,
both proprietary and public-domain.
An input filter called psfilter provides a simple ASCII-to-PostScript
conversion. Normal PostScript format files will not be affected. An output
